Description

[Detailed explanation of the idea] The present invention relates to improvements in packaged insect repellents.

Paradichlorbenzene, used for insect repellent on clothing, etc.
Sublimable insect repellents such as naphthalene and camphor are generally hermetically packaged with a transparent gas-impermeable sheet, such as cellophane, and the four corners of the packaging bag are cut open at the beginning of use to allow sublimation and dissipation of the insect repellent. is possible.

However, with this packaged insect repellent, it is necessary to cut out the four corners of the packaging bag to form ventilation openings each time the bag is used, which is very complicated and has the disadvantage of producing cutting waste.

By the way, recently, in order to eliminate the need for cutting openings at the four corners of a packaging bag, the entire packaging bag is made of a breathable sheet such as non-woven fabric, Japanese paper, Western paper, etc., or one side of the packaging bag is made of non-woven fabric, etc. A gas-permeable sheet with a transparent gas-impermeable film on one side has been proposed and put into practice.

However, with the above-mentioned packaging bag, the sublimation and dissipation rate of the packaged insect repellent is fast and there is a problem in sustainability.

The present invention has been made in view of the above-mentioned points, and is a packaged insect repellent in which the insect repellent is stored and sealed in a packaging bag formed of a gas-impermeable sheet, in which a slit is formed in the packaging bag, and the insect repellent is sealed. By covering the slit with a breathable non-woven fabric, there is no need to cut out the four corners of the packaging bag to form ventilation holes at the beginning of use, and therefore no chips are generated, and the insect repellent can be sublimated and dispersed. One or more breathable sheets are releasably attached one by one to the outside of the nonwoven fabric provided to cover the slits for the purpose, and the breathable sheets are peeled off one by one as necessary. It is an object of the present invention to provide a packaged insect repellent which can obtain an appropriate amount of sublimation and emission of the insect repellent and has excellent sustainability by appropriately adjusting the amount of gas permeation through the slit.

Next, one embodiment of the present invention will be described with reference to FIGS. 1 and 2.

The packaging body 1 is formed into a flat shape by using a transparent gas-impermeable sheet 2, such as cellophane having a thermoplastic synthetic resin film on the inner surface, and bonding each joining edge by heat welding, pasting, etc. There is.

A sublimable insect repellent 3 such as paradichlorobenzene, naphthalene, camphor, etc. is housed within this packaging body 1.

Similarly, this insect repellent 3 does not necessarily need to be shaped and may be in the form of granules.

The packaging body 1 has a slit 4 formed approximately in the center of its upper surface or both upper and lower surfaces.

Although the slit 4 is formed in the long side direction of the packaging body 1 in FIG. 1, it may be formed in the short side direction.

Further, the slit 4 may be formed not only in one line but also in a plurality of lines, such as two or three lines.

The slit 4 is covered with a nonwoven fabric 5 formed into a belt shape.

That is, the nonwoven fabric 5 is thermally welded to the inner surface or upper surface of the packaging body 1 around the slit to cover the slit 4.

Furthermore, in the present invention, as shown in FIG.
are adhered to each other so that they can be peeled off one by one.If all of the breathable sheets 7 are peeled off at the time of use, the amount of ventilation corresponding to the ventilation holes of the nonwoven fabric 5 itself that closes the slits 4 can be obtained. As shown in Figure 2B, by leaving the required number of breathable sheets 7 (one sheet or several sheets) and peeling off the others, the ventilation holes are closed according to the number of sheets pasted, so that the amount of ventilation can be controlled and adjusted. It has become.

As the helmet and the breathable sheet 7, a sheet made of polyethylene or polypropylene which itself has breathability, or a non-breathable sheet made of nylon or the like with small ventilation holes perforated therein is used.

Further, a release paper (not shown) made of a gas-impermeable sheet formed into a band shape is adhered to the upper surface of the air permeable sheet on the upper surface of the slit 4 of the packaging main body 1, if necessary.

The release paper is then peeled off before use.

By using the gas-impermeable release paper in this manner, the packaged insect repellent of the present invention can be easily stored before use.

Therefore, with the packaged insect repellent of the present invention, there is no need to cut out the four corners of the packaging bag to form ventilation holes before use.
It is taken out from the storage body and used (11 (if a release paper is attached, peel off the release paper)).

Then, the packaged insect repellent 3 is sublimated and diffused through the slit 4 covered with the breathable sheet 5, thereby acting as an insect repellent for clothing and the like.

Furthermore, in the present invention, by appropriately setting the number and size of the slits 4 and the amount of gas permeation through the breathable sheet 5, the amount of gas permeation through the packaging bag can be freely set, and appropriate sublimation and dissipation of the insect repellent can be obtained. , sustainability is also good.

The amount of gas permeation through the nonwoven fabric 5 provided so as to cover the slit 4 can be determined by peeling off a plurality of breathable sheets releasably attached to the outside of the nonwoven fabric 5 one by one from the outside. This is done by appropriately opening the ventilation holes in the nonwoven fabric.

3 and 4 are other embodiments of the present invention.

In this embodiment, a pillar-shaped insect repellent 6 is packaged and housed in a packaging body 1 made of a transparent gas-impermeable sheet 2.

Then, the top surface or (and) bottom surface of this packaging main body 1,
A slit 4 is formed on the side surface, for example in the longitudinal direction, and the slit 4 is covered with a band-shaped nonwoven fabric 5, and a plurality of breathable sheets are adhered to the upper surface of the nonwoven fabric 5.

Further, if necessary, a gas-impermeable release paper is attached to the breathable sheet on the upper surface of the slit 4.

In addition, for the present invention, the form of the packaging main body 1, the packaging means,
The process and the type of stacking of the gas-impermeable sheet do not matter.

In the form of a packaging bag, the edges to be joined may be three sides as in the embodiment, or four sides, and the packaging bag may be a single bag or a plurality of bags connected.

The nonwoven fabric may be not only a single nonwoven fabric, but also a separate paper, western paper, or a bonded surface of the nonwoven fabric may be laminated with a gas permeable thermoplastic resin.

Since the present invention is constructed as described above, there is no need to cut out the four corners of the packaging bag to form ventilation holes prior to use, and the insect repellent can be sublimated and dissipated without generating chips. One or more breathable sheets are releasably attached one by one to the outside of the non-woven fabric covering the slits, so that the non-woven fabric can be removed by peeling off the breathable sheets one by one as needed. It is possible to adjust the opening amount of the ventilation holes, and therefore, the insect repellent can be sublimated and dissipated in an appropriate manner, and the insect repellent has effects such as good sustainability.
